To' all whom z't may concern:

Be it known that I, Louis E. Conso, a citizen of'the United States,residing at Enid, in thecounty of Garfield and State of Oklahoma, Vhaveinvented certain new and useful Improvements in Intake-Manifold Gaskets'and I do declare the following to be afull,` clear, and exactdescription of the such as will enable others skilled 1n the art towhich it appertains to make and use the same.

Iy invention has for its object to provide a novel form of asket to beused betiveen the intake manifo ds engines and the carbureters thereof,said gasket embodying electrlc resistance wires for heating the fue] as1t asses through the usual opening of the ged? 1 A further object is toprovide a device of the class which may be easily a d inexpenandmarketed, easily and quickly applied. andbtne which will be and fullydescrlbed and claimed, the descriptive matter being supplemented by theaccompanying drawin which form a part of this` specification an inwhich:

igure 1 is a top plan view of one of the gaskets a plied to use andshowing a portion. of tlie--Vintake manifold in horizontal section;

Fig. 2 is a in Fig. 1;

Fig. 3 is a longitudinal section on the plane of theline 3 3 -of`Fig. 1showing the gasket applied A Fig. 4 is a transverse section on the planeindicated by the line 4--4 of Fig. '3;

Fig. 5 is a perspective view of the central lamination whlch carries theresistance Wires;

Fig. 6 is a view similar to Fig. 3 showing a different form ofconstruction; and

ig. 7 is a transverse section of Fig. 6 on top plan view of the gasketseen l the plane of the line 7-7 thereof.

drawings above briefly described.

gasket, said lamination being preferably formed of mica although anyother other preferred material could be employed. Lammation l is formedwith a central openin shown in Figs. (i and 7. lVhen this is done thebridge in question is necessarily made either totall or partiall)vseparate from the gasket 1 and suitablx secured to the latter, whereaswhen thc bridge is of rectilinear formation, it magi` be formedintegrally with the lamination 1 as shown for instance in Fig. 5.

Regardless of its exact shape, the bridge 5 is provided in its oppositeedges with notches and the lamination 1 is formed vit 1 perforations 8adjacent the edge of the opening 2. a pair of thread-like resistanceWires 9 being trained to and fro across the opening 2 and laced into theaforesaid notches and perforations. The ends of these wires are utilizedfor supplying current thereto in a manner to be hereinafter described.

]aminations 10 as will be clear from Fig. 5, while the. other ends ofsaid wires pass through the laminations at l-l to one side of thegasket. extend along this side a. suitable distance as shoivn at l5,then return through tesimal thickness. assage of the Wires through thelaminations of the gasket holds one end of said laininations togethersecurely and a wire staple 18 is employed for holding the laminations atthe other end ot' the gasket in proper relation. 6 A suitable bindingpost 19 is adapted to be clamped by one of the bolts l. said boltbeingprovided with a ground wire 20 and with another wire -21 insulatedtherefrom, the free ends 13 of the wires 9 being elec- 1-0 tricallyconnected with the wire '21 and insulated by anv suitable means such asthe beads 22 shown in lFig. 1. In Fig. 5. wire 20 is shown leading froma batter)v '23 and grounded at 24: on the frame of the machine, 15 onthe motor, or anni* other preferred Ipart, while wire 21 leads from saidbatter)v to the ends 13 of the' resistance wires 9. It thus follows thatwhen the gasket is clamped in place as shown in Figs. 3, l. 6 and 7. thecurrent will {iow from the battery through wire 21 to the resistancewires 9. from the latter the current will ground by means of the plates15 which contactJ with the carbureter or intake manifold. and from this25 ground the current will return to the bat-V ter),r through the wire20, a suitable switch 25 being provided for breaking the circuitwhenever required.

By the use of the device, extremely advantageous results can be obtainedsince ,closing of the switch 25 will raise the teniperature of theresistance wires 9 sufficiently to, properly heat the mixture passingfrom the carbureter through the intake manifold to the engine cylinders.thus rendering this mixture sufficiently volatile to tire quickly andeasily in the engine.

Since probably the best results are obtained from the details shown anddescribed, these details are preferably employed, but. within the. scopeot the invention as claimed, numerous minor changes may well be. made.

I claim: 1. Asn intake manifold gasket comprising a lamination ofinsulatin material having an opening through whic i the fuel passes, abridge of insulation spanning said opening, the edges of said bridgehaving not-ches and said lamination having perforations ad 60 jacent theed e of the opening, resistance wiring traine to and fro across saidopen- -ing and lacedinto vsaid perforations an notches, the wires fromeach side of sai opening extending around the opposite edge of said bride and heilig held. from' contact 55 with each ot ier by engagement insaid perforations and notches, t-he terminals of said wiring beinglocated for supplying current thereto, and other laminations applied tothe upper and lower sides of said first named lamination.

'2. An intake manifold gasket having an opening through which the fuelpasses an comprising a plurality of laminations of insulating material.resistance wiring trained across said opening and carried by one o theintermediate laminations, one terminal ot' said wiring extending to theedge of the gasket between certain of the laininations for connectionwith a current supply wire, and the other terminal of said wiringpassing through said lamination to one side o the gasket. and beingclenched to hold one end of said laminations together, and means forsecuring the other ends of said laminations together.

3. An intake manifold gasketr having an opening through which the fuelpasses and comprising a plurality of lamiiiatioiis of i insulation, oneof the intermediate laminations having a bridge of insulation across itsopening. said bridge having notches in its l edges and said laminationhaving perforations adjacent the edge of said opening. a pair ofresistance wires trained to and fro across said opening and lacedthrough said perforations and notches. one end of said wires extendingto the edge of the gasket between the laminatons for connection with acurrent suppl1 wire and the other ends of 90 said wires passing throughsaid laininations to one side of the gasket., then passing buck throughsaid laminations to the other side of the. gasket and being clenched. tohold one end of said laminations together, ground plates secured to theportions of the wires exposed at said first named side of the gasket,and means for securing the ends of said laminations opposite said groundplates together.

In testimony1 whereof I have hereunto setI my hand in the prese-nce oftwo subscribing .l witnesses.
